BEARING FOR SLIDE-RODS FOR TEXTILE MACHINERY.

Application filed July 5, 1906.

c To all whom it may concern:

Be it known that I, CHARLES E. Lovn- JOY, ofv Lowell, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Bearingsfor Slide-Rods for Textile Machinery, ofwhich the following description, with the accompanying drawings, is aspecification.

Like letters on the drawings denote like parts.

My invention relates to textile machines for location in an atmospherecontaining fibrous flyings, and to the combination therein of a rod anda lateral bearing adapted for relative longitudinal traverse of the rodand the bearing and to that class of such combinations in, which thebearing is provided with means for preventing such fibrous materials asmay collect upon the rod from packing between the rod and the bearingand causing excessive friction in the bearing or the sticking of the rodtherein.

- and the rod in every direction lateral to the rod, each part having arod-engaging portion that terminates in an open space which surroundsthe portion and separates the part from the other parts, one or more ofsuch parts having a rod-cleaning edge in angular relation with the rodat an intersection of a surface of the part with the rodengagingportion.

The hearing may be fixed and the rod movable or the rod maybe fixed andthe bearing movable relatively to the frame of the machine.

The rods of some textile machines are continually enveloped in anatmosphere containing fibrous flyings. Whether the rod slides instationary bearings or is stationary having sliding bearings, the flyingfibers light upon the rods. If the rods are not kept free from fibersthey pack fibers into their bearings and eventually stick. Oiled rodsgather fibers quicker and stick sooner than others. Inring-spinning-frames the lifter-rods can be cleaned by hand withoutdifhculty and frequently, but the separatorrods cannot. If thebuilder-motion is of a Specification of Letters Patent.

common type, the sticking of the separatorrod stops the ring rail andyarn-bunches form on the bobbins, causing waste of yarn and service. Thewhole duty of some operatlves is to stop ring-spinning frames, clean theseparator -rods and their partially packed bearings by hand, and tostart the frames again. The preferred form of my invention is adapted tothe bearings of such separator-rods and includes a power-operatedcleaner that effectually prevents the sticking of the rod in its bearingand obviates the necessity for stopping the machine for hand-cleaning.

In the drawings: Figure 1 is an elevation seen when looking lengthwiseof a ringspinning frame of bearings of the preferred form of myinvention applied toa separatorstand of a ring-spinningframe. .Fig. 2 isan elevation of the same parts seen when looking fromthe interior of andcrosswise of the frame. Fig. 3 is a cross-section of the bearing and rodat line 1-1 of Fig. 1. Fig. 4 is a cross-section of the bearing and rodat line 2-2 of Fig. 1. Fig. 5 is a horizontal-section at line 3-3 ofFig. 1. Fig. 6 is a front elevation of a portion of a ringspinning-framewith bearings of my invention applied to a lifter-rod. Fig. 7 is across-section at the line 4-4 of Fig. 6. Fig. 8 is a diagrammatic viewof parts of a ring spinning-frame that are old in the art. Fig. 9 is aplan showing the usual locations of a separator-rod and of a lifter-rodrelatively to other parts of a ring-spinning frame.

The preferred form of my invention is represented in Figs. 1, 2, 3, and4 in the two bearings for a separator-rod and in Figs. 6

and 7 in the two bearings for a lifter-rod.

make one pair. The parts 43 and 44 shown in Figs. 1, 2, and 4 make theother pair. The four parts are all integral with the stand 1 and locatednear to one another with the pair 41 and 42 at a slight distance in thedirection of the rod from the pair 43 and 44. Each part has a verticalplane surface for' engagement or contact with the rod. The parallellines 6 and 6 seen in Fig. 3 extend lengthwise of the spinning-frame.They are horizontal sections of such vertical planesurfaces of the partsll and 42. The parts 4:1 and il-2 control the relative lateral movementof the bearing and the rod in opposite directions crosswise of thespinningframe. The parallel lines 61 and 61 seen in Fig. 4 extendcrosswise of the spinningframe. They are horizontal sections of suchvertical plane surfaces of the parts 43 and let. The parts $3 and i lcontrol the relative lateral movement of the bearing and the rod inopposite directions lengthwise of the spinning-frame. Taken together,the four parts 41, 4-2, 43, and 4d are shaped and lo cated to controlthe relative movement of the bearing and the rod in every directionlateral to the rod. Each of the four parts ll, 42, 4- 3, and adhas twohorizontal end surfaces. Each such horizontal end surface intersects thesaid vertical plane surface of the same part in a right-angled edgewhich is perpendicular to the rod. Each such edge is eflicient as arod-cleaning or rod scraping edge. Each such part has a rod engaging ortouching portion that terminates in and is entirely surrounded by anopen space in which the part ooes not touch the rod, in which fibers maymove freely, and which completely separates the rod engaging or touchingportion of the part from the rod engaging or touching portion of everyother such part. Horizontal sections of such spaces are seen in Fig. 3at 7 and 7, and in Fig. 4 at 71 and 71. When a rod-cleaning edgecompletely dislodges a fiber from the rod, it may escape from thebearing, and rod through such a space. When a rod-scraping edgepartially dislodges a fiber from the rod, the fibermay project into thespace and during the continued relative motion of the rod and thebearing in the direction of the rod the fiber may be struck by some partof the bearing and wholly dislodged from the rod. When a fiber is caughtbetween the rod and a rod engaging or touching portion of a part of thebearing, he relative motion of the rod and the bearing in the directionof the rod may roll the fiber, detaching it wholly or partially from therod. It facilitates the cleaning of the rod to give to the part of thefiber which is free from pressure during the rolling freedom of motionin the space which entirely surrounds the rod engaging or touchingportion.

My invention, as applied to the bearings for the nonrotatingseparator-rods of a ringspinningframe in an atmosphere loaded withfibrous fiyings, has been long con tinued in operation under observationwith the result that no separator rod has been seen to stick in one ofmy bearings notwithstanding that, during the period of observation,neither the rod nor the bearing nor the power-operated cleaner of thebearing was cleaned by hand. It is thought that, prior to my invention,there has been no instance ofv a non-rotating slide-rod surrounded by anatmosphere charged with fibrous flyings and located in a textilemachine, which has not required the occasional cleaning by hand of therod or of its bearings or of some mechanical cleaner connectedtherewith.

It is not essential to my invention: that the number of parts forengaging or touching the rod shall be four or that any such part shallbe integral with the hearing or fastened to a stationary support or thatthe rod engaging or touching portion of any such part shall be a planeor that any two such portions shall be parallel or at rightangles or at.a slight distance apart in the direction of the rod. It is essential tomy invention that such parts taken together shall control the relativemovement of the bearing and the rod in every direction lateral to therod, that each such portion shall be surrounded by a space in which thepart does not touch the rod and that some such part shall have arod-cleaning edge.
